Docker化Laravel应用GitHub Actions流水线HTTP 500错误求助

问题背景 #

本地环境执行docker-compose exec -T app php artisan test可正常通过Docker化Laravel应用的测试，但在GitHub Actions流水线中，某个预期返回200的测试出现HTTP 500错误。

已尝试的排查手段 #

• 改用GitHub Actions的services替代docker-compose部署应用
• 确保.env.example和nginx/conf.d/laravel.conf.example正确复制为正式配置文件
• 验证配置文件内容的正确性
• 检查容器内文件权限
• 查看app和webserver容器日志
• 使用与本地相同版本的docker-compose
• 强制执行数据库迁移命令
• 添加等待时间确保init.sh脚本执行完成
